Electronic Configuration: The electronic configuration of an atom shows the packing of the electrons in the shells and the orbitals. There are two forms of writing the configuration: One is the full form which shows the packing for all the electrons, and the other is the abbreviated form which...
Explain briefly. (d) Explain how the electron configuration of the arsenic atom in the ground state is consistent with the existence of the following known compounds: Na 3 As, AsCl 3 , and AsF 5 . a) 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 3 b) for the two electrons in ...

Noble Gas Core Electron Configurations Recall, the electron configuration for Na is: Na: 1s2 2s2 2p6 3s1 We can abbreviate the electron configuration by indicating the innermost electrons with the symbol of the preceding noble gas. The preceding noble gas with an atomic number less than sodium...
Electron Configuration:Electrons in atoms exist in orbitals. The electron configuration for an atom shows the specific orbitals that the electrons occupy for that atom. Electrons occupy the lowest energy orbitals available first. The electron configuration shows the principal level and sublevel that t...
